Abstract
An optical recording method to record information with a mark length recording method, where an amorphous mark and a crystal space are recorded only in the groove of a substrate having a guide groove, with the temporal length of the mark and the space of nT (T denotes a reference clock period; n denotes a natural number). The space is formed at least by an erase pulse of power Pe; all the marks of 4T or longer are formed by a multi pulse alternatively irradiating a heating pulse of power Pw and a cooling pulse of power Pb while Pw > Pb; and the Pe and the Pw satisfy the following relations: 0.15 ≤ Pe/Pw ≤ 0.4, and 0.4 ≤ τw/(τw+τb) ≤ 0.8, where τw denotes the sum of the length of the heating pulses, and τw, denotes the sum of the length of the cooling pulses.
